Language

This study will examine the effect of TMS on people with stroke and aphasia as well as healthy individuals.

Language is a signature human cognitive skill, but the precise computations that support language understanding remain unknown. This study aims to combine high-quality human neural data obtained through intracranial recordings with advances in computational modeling of human cognition to shed light on the construction and understanding of speech.

Williams syndrome (WS) is a neurodevelopmental disease characterized by mild to moderate intellectual disability and an extremely heterogeneous cognitive profile. Research has outlined two main features of WS: an atypical social behavior associated with surprising language abilities, and a hyperacusis. The purpose of this project is to investigate the relationships between both these abilities, and particularly the role of the hyperacusis on language abilities. The hyperacusis would be crucial in developing language skills: the apparent strength in the verbal domain could rely on Phonological Short Term Memory (PSTM) more in individuals with WS than in typically developing individuals. In addition, the investigators will compare individuals with WS to individuals with Down syndrome (DS): DS is often associated to strong limitations in the PSTM with poor language abilities. To this end, the investigators will use a highly innovative approach including physiological assessments (EEG-NIRS protocol) and questionnaires. The performance of people with WS will be compared to those of participants with DS and TD participants of same DA and cognitive assessments.

Patients with stroke frequently suffer from aphasia, a disorder of expressive and/or receptive language, that can lead to serious health consequences, including social isolation, depression, reduced quality of life, and increased caregiver burden. Aphasia recovery varies greatly between individuals, and likely relies upon the capacity for neuroplasticity, both at a systems level of reorganized brain networks and a molecular level of neuronal repair and plasticity. The proposed work will evaluate genetic and neural network biological markers of neuroplasticity associated with variability in aphasia, with a future goal to improve prognostics and identify therapeutic targets to reduce the long-term burdens of aphasia.

The investigator proposes to examine the effects of excitatory transcranial magnetic stimulation (TMS) combined with semantic feature analysis (SFA) language therapy to improve word-finding abilities in stroke survivors with aphasia (SWA).

The goal of this clinical trial is to learn if the Talk With Me Baby (TWMB) program improves the home-language environment for at-risk families with children ages two to six months when primary care providers deliver the program during well-child checkups. The main question it aims to answer is: Will the TWMB program increase the time a caregiver talks to their infant? Participants will: 1. Come to at least four well-child checkups 2. Receive the TWMB program from the provider during the checkups 3. Record their conversations with their infant before they receive the program and after they receive the program four times.

This study will examine the effect of TMS on people with stroke and aphasia as well as healthy individuals.

The purpose of this qualitative study is to find out which technological translation tools can be used to improve Dutch-speaking care in all Brussels out-of-hours primary care services.

The purpose of this study is to understand how transcranial magnetic stimulation affects how quickly, easily, and accurately a person read. Transcranial magnetic stimulation is a technique that uses magnetic fields to briefly affect how well certain brain regions function. The investigators would like to better understand how long the effects of transcranial magnetic stimulation occur in the reading system and at what point the effect is strongest in this system. The main questions it aims to answer are: 1. At what point after stimulation are the greatest effects on behavior seen 2. How excitatory and inhibitory stimulation affect behavior Researchers will compare stimulation types against a sham condition to see effects on reading and language behavior. Participants will be asked to * undergo reading, language, and cognitive testing * receive an MRI * receive TMS stimulation * perform language, reading, and motor tasks
